Could be done, but it sounds like more of a camper than a cruiser. I am looking for something which is equivalent in function to the Maine Cat 30 catamaran, where a family can live aboard comfortably for several months per year, but not permanently. For that, we need the cooking equivalent of an efficiency apartment, and space to move around in nice weather. Belowdecks is just for sleeping and bathroom.
Maybe it can't be done, but an inexpensive cruiser would fill a niche that no other design seems to have. I think the Maine Cat 30 is right around $200K now, and a harry version would sail rings around it.
